We are having our end-of-the-year family picnic on June 4 at 5:00 p.m. at Gladys Potter Park (aka Humboldt Park). Please bring a picnic dinner for your family and ESNS will supply the watermelon! This is a fun time for all families, new and old, to get together to visit and play. Please RSVP on our Facebook event page. We hope to see you there!
